摘要
根据雷达天线车液压系统的工作特点,搭建了一套电液比例泵控试验系统,并对系统的工况和特性进行分析,提出了基于比例流量(Q)和比例压力(P)的复合控制策略,设计了一种基于神经网络的自适应PID控制器,对系统的压力和流量进行复合控制。利用AMESim仿真软件对该电液比例泵控系统进行了全数字化建模与仿真,仿真结果表明,所设计的复合控制器能较好地实现系统压力和流量的跟踪控制。对泵控系统进行试验,结果验证了所设计系统的可行性,为实际电液比例泵控系统的研究和应用提供了参考。
According to the operating characteristic of the hydraulic system for radar antenna vehicle,an electro-hydraulic proportional pump control test system is constructed.The operating status and characteristic of the system are analyzed and the compound control strategy based on proportional flow（Q） and proportional pressure（P） is put forward.An adaptive PID controller based-on neural network is designed,which can control both pressure and flow of the system.The digital model of the electro-hydraulic proportional pump control system was established and the simulation was conducted by use of AMESim software.The simulation result shows that the compound controller can realize the tracking control of the system pressure and flow preferably.The test of pump control system is done,and the feasibility of the designed system is validated.
